What amount of active ingredient,in grams (g),is present in 2 oz of hydrocortisone 4% cream?

Rationale

There are 2.4 grams of active ingredient in 2 oz of hydrocortisone 4% cream.

To calculate the amount of active ingredient in the cream, we need to convert ounces to grams and then apply the percentage concentration. Since 2 ounces equals approximately 56.7 grams, 4% of this total is 2.4 grams, demonstrating the correct answer.

A (0.24) YOUR ANSWER

This option represents a miscalculation based on a misunderstanding of the percentage. If 0.24 grams were the active ingredient, it would imply a much lower concentration than 4% in the total weight of the cream, which is not the case here.

B (2.4) CORRECT

This choice correctly represents the calculation of the active ingredient. With 2 oz converted to about 56.7 grams, calculating 4% of this total gives 2.4 grams, aligning perfectly with the requirement of the question.

C (24) YOUR ANSWER

This option suggests a significant overestimation of the active ingredient. A total of 24 grams would imply a concentration of 42.3%, which exceeds the stated 4% concentration in the cream. Therefore, this value cannot be correct.

D (60) YOUR ANSWER

This choice is also an overestimate, indicating that 60 grams of active ingredient would represent a concentration of over 105%, which is impossible for any solution. Thus, this option is not plausible given the 4% concentration.

Conclusion

The calculation of the active ingredient in hydrocortisone 4% cream reveals that there are 2.4 grams present in 2 ounces. Understanding the conversion of ounces to grams and the application of percentage concentration is crucial in deriving the correct answer. The other options fail to reflect accurate calculations based on the given percentages and total weight.
